Pregnancy doesn't necessarily mean an increased risk of recurrence for hormone-dependent breast cancer patients, according to a new study released Wednesday at the European Breast Cancer Conference in Vienna.

Pregnancy doesn't necessarily mean an increased risk of recurrence for hormone-dependent breast cancer patients, according to a new study released Wednesday at the European Breast Cancer Conference in Vienna.

Breast cancer is the most common cancer among women of childbearing age. As more women started a family later in life and the survival rate of breast cancer patients has improved in modern society, the number of patients who intended to have children after their treatment is rising.

However, former studies believed that pregnancy would lead to the change of hormone level and cause a new or more aggressive breast cancer cells.

Study results of the Bordet Institute from Brussels upset this conventional wisdom and pointed that pregnancy doesn't mean recurrence risk to salvaged patients of hormone dependent breast cancer.

Their study was carried based on comparisons of 1, 207 breast cancer patients from difference countries. About 30 percent of surveyed patients relapsed to a breast cancer during pregnancy or 4.7 years after pregnancy, of which 57 percent are hormone-dependent breast cancer patients.

The findings showed that there was no difference in the recurrence rate between those experience pregnancy and the ones don't have; in addition, pregnancy didn't have impact on the survival rate of breast cancer patients. In short, there was no difference between women with hormone dependent breast cancer and other forms of breast cancer.

Hatem A. Azim Jr, head of the research team, also pointed that patients who became pregnant within two years after breast cancer diagnosis obviously have a better disease-free survival than those who were not pregnant.

Therefore, breast cancer patients have no risk of recurrence when become pregnant two years after treatment, according to him.

The 8th European Breast Cancer Conference was held Wednesday to Friday in Vienna. The Europe's largest forum on breast cancer was expected to attract over 5,000 delegates from around 90 countries worldwide.
